I am using Boomaga 3.0 under Linux Mint 20.1 and printing to a networked HP LaserJet Pro M118. The printer prints duplex as it did under 19.3 but when using Boomaga to print through the LaseJet it prints single pages in both full page and booklet format. I have set it up exactly as described in 3. Printing from within Boomaga using an automatic duplex printer. Is there anything I can do to regain the use of Boomaga - I dearly miss printing booklets.
